You might want to check out my tutorial on Terrain Mapping.Â
The dpi doesn't matter - it's the pixel size - a 256x256 pixel image will give you jaggies where an origianlly 2,048x2,048 will not - doesn't matter if it's 300dpi or 10dpi - it's STILL x-amount of pixels by x-amount of pixels. The higher the cleaner - unfortunately it'll also take more memory but looks better.Good luck- -Lew ;-)
Well that's good to know...I'll pass that on to the ladies at work as well (seems we have a dpi debate goin' on). Scratch that one then lol..... So maybe try that 'diffuse' button under 'erosion'? Unless....Lorne, are you using an image on a procedural terrain? That will always make jaggies in the geometry....from my own experience.
Chipp Walters, I read through your tutorial, but I can't see anything new I should be doing. Monsoon, "Diffues Button" I don't see that in Chipps tutorial do you mind telling me where it is in Vue? Thundering1, you said: "it's the pixel size - a 256x256 pixel image will give you jaggies where an origianlly 2,048x2,048 will not - doesn't matter if it's 300dpi or 10dpi - it's STILL x-amount of pixels by x-amount of pixels. The higher the cleaner" I thought this was the case too, but I made the height map for this image at 2400 x 2400 pixels and it still looks jagged. Here's the steps I took 1. I created a Standard Terrain (the default is 1000 x 1000) I changed the size to 512 x 512. I also tried with the terrain set to 1000 x 1000 2. Then I created an image (height map) in Photoshop with these settings. (2400 x 2400 pixels) -300 ppi -Saved as greyscale image 3. I then selected "Picture" and loaded my image image. 4. Rendered the file. One thing that still confuses me is how do I know what size to make my "StandardTerrain" and does it matter? If it does how do I determine the correct size? I also remember read in the Vue manual that Standard Terrains are lower in quality than Procedural Terrains. So I guess there's no way to create a custom terrain using heightmaps in Vue unless you want jagged edges. I was hoping I could use a custom height map I created for a project. Maybe the next version of Vue will address this. It's too bad Vue cannot use heightmaps with procedural terrains either. This is disappointing... Thanks for all of your help though!

Check out what I say about Diffuse here. It should do the trick.Â

I am so sorry. Color me VERY stupid!!! It's the Diffusive control. This the the right link!! (text at the bottom of the page) sorry again ;-)Â
Gradient maps typically loose their smoothness if you push too much towards the white or black extremes. There are few colours between black and almost black for anti-aliasing. You can sort of see the effect in the above photoshop image where I've used the levels adjustment control to highlight the shadow detail. Note the pixelated edges around the darkest "shelves" on the modified image. The transitions are much smoother towards the mid-range. -- Mark
